Method and system for testing temporal latency in device having optical sensing component and touch-sensitive display component
Abstract:
A method and system for determining a camera-to-display latency of an electronic device (100) having a camera (134) and touch-sensitive display (108) are disclosed. In one example embodiment, the method (500) includes receiving (511) first light (136) at the camera, and essentially simultaneously receiving second light (138) at a first photosensitive structural portion (102, 602). The method (500) further includes detecting (512) a first simulated touch input at the display (108) in response to a first actuation of the first photosensitive structural portion (102, 602), receiving third light (140) at a second photosensitive structural portion (104, 604), the third light being generated based at least indirectly upon the received first light (136), detecting (514) a second simulated touch input at the display (108) as a result of the receiving of the third light (140), and determining the camera-to-display latency based at least indirectly upon the touch inputs (516).
Abstract(Chinese):

公开了一种用于确定具有相机（134）和触敏显示器（108）的电子设备（100）的相机到显示器延迟的方法和系统。 在一个示例性实施例中，方法（500）包括在相机处接收（511）第一光（136），并且基本上同时在第一感光结构部分（102,602）处接收第二光（138）。 方法（500）还包括响应于第一感光结构部分（102,602）的第一致动，在显示器（108）处检测（512）第一模拟触摸输入，在第二感光体处接收第三光（140） 结构部分（104,604），所述第三光源至少间接地基于所接收的第一光（136）产生，由于接收到所述第三光源（136）的所述第三光源 光（140），并且至少间接地基于触摸输入（516）确定相机到显示器的等待时间。
